Application tied April 13,1903. Serial No. 152,419.

, zen of the French Republic, residing at 6 Rue de Savoie, Paris, France, have invented certain new and useful Improvements Relating to Devices for Stretching Paper or other Substances, lof which the following is aspecification. I

This invention relates particularly to improvements in reglets designed to be engaged in connection with a stretcher-frame provided with channels or grooves to receive the reglets; and the object is yto provide a reglet that will have a lateral spring-yielding tendencyl at its ends, the said spreading action being materially assistedby means of springs ar- ,ranged in the reglets. The stretcher-frame,

it will be understood, is designed for stretching sheets of paper, fabric, leather, and similar materials.

Reference is-to be made to the accompanying drawings, in which- Figure 1 is a view of the underneath surface of the reglet'. Fig. 2 is a vertical section on the line A B in Fig. 1. Fig. 3 is a plan of the uppermost surface of a reglet. Fig. 4 is a section on the line C D in Fig. 1. Fig. 5 is a section on the line E F in Fig. 1. The reglet consists of a bar of wood or other suitable material and of suitable length trape- The inner or under surface of the reglet has outwardly-opening longitudinal channels ct b, which extend from a block portion c, and extended from the side walls of the channels are shoulders ol, which serve as supports for longitudinally-curved springs e, the ends of said springs bearing against one wall, while the center portion bears against the It will be noted that the channels or slots extend entirely through to the outer face a and the material at one Side is of less thickness than the material at the opposite side. Thus the lesser thickness may be readily sprung outward when the device is inserted in the channel of a stretcher-frame.

In order tofacilitate the formation of the recesses a b and particularly the anges d, Fig. 4, there may'be'formed upon the outer face a of the reglet a groove which extends` throughout the entire length-that is, it extends over the block portion c, as clearly indicated in Fig. 3, and communicates with the outwardly-opening slots or channels.`

1n the operation the material to be stretched is placed over the stretcher-frame and extended over the channels thereof. Then the reglets may be forced downward into the channels carrying thepaper therein. The lateral yielding or resiliencr of the reglets will clamp the paper rmly against the opposite walls of the channels in the' frame.

Having thus described my invention, I claim as new and desireto secure by Letter Patent- `1. For use in connection with a stretcherframe having channels, of reglets consisting of lengths of wood, the end portions of which are separated by longitudinal grooves or slots, the material at one side of the slots or grooves being thinner than the material at the opposite side, and curved springs arranged in said slots and bearing against the opposite walls thereof.

2. For use in connection witha stretcherframe having'channels, of regletsfor engaging in said channels, each reglet consisting of' RACHEL GAUGUET.
